BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to air conditioning systems formotor vehicles and, more specifically, to a condenser with an integralreceiver dryer for an air conditioning system in a motor vehicle.

2. Description of the Related Art

It is known to provide a condenser for an air conditioning system in amotor vehicle. The condenser typically receives a fluid such as arefrigerant in a vapor phase, at a reasonably high temperature, andcools the vapor phase to transform it to a liquid phase. The condensernormally includes a plurality of tubes extending between oppositeheaders. The condenser also includes a plurality of cooling finsdisposed between the tubes. One type of condenser, often referred to asa multi-pass condenser, includes a plurality of baffles placed in one orboth of the headers to direct the refrigerant through a plurality offlow paths. As the refrigerant flows in a back and forth pattern throughthe condenser, heat is transferred from the vapor phase of therefrigerant to condense to the liquid phase. The liquid phase continuesto flow through the tubes of the condenser until it reaches an outletwhere it is drawn off and used in the air conditioning system. When bothliquid and vapor phases are present, continued flow of the liquid phasethrough the tubes decreases the overall efficiency of the condenser asthe vapor phase is hindered from contacting and transferring heat to thetubes. Further, the liquid phase of the refrigerant occupies spacewithin the tubes, thus reducing available interior surface area for heattransfer.

It is also known to provide a separate receiver dryer for storage ofexcess refrigerant from the condenser and to remove any moisture fromthe refrigerant in the air conditioning system. An example of a separatereceiver dryer for a condenser in an air conditioning system isdisclosed in U.S. Pat. No. 5,755,113. In this patent, a separatereceiver dryer fluidly communicates with a condenser. The receiver dryerincludes a fluid inlet for receiving a two-phase refrigerant mixturefrom the condenser and two outlets, both of which direct refrigerantback to the condenser after phase separation. The receiver dryer alsoincludes a quantity of desiccant material to remove moisture from thetwo-phase refrigerant mixture.

Other examples of receiver dryers used with condensers are disclosed inU.S. Pat. Nos. 5,537,839, 5,546,761 and 5,666,791. However, thesereceiver dryers utilize separate containers, which are attached to theheader or manifold of the condenser by various means. In some cases, theattached containers do not contain the desiccant material. Since thereceiver dryer is a separate part, it requires additional space,fittings and brackets to attach it to the air conditioning system.

Although the above receiver dryers have worked well, it is desirable toincorporate a receiver dryer into a condenser. It is also desirable toincorporate a receiver dryer into a manifold of a condenser. It isfurther desirable to provide a condenser with a receiver dryer havingfewer parts and compact installation.

SUMMARY OF THE INVENTION

Accordingly, the present invention is a condenser including a firstmanifold, a second manifold spaced from and opposing the first manifold,and a plurality of fluid carrying tubes extending between and in fluidcommunication with the first manifold and the second manifold. Thecondenser also includes a receiver dryer being internal to and integralwith a housing of one of the first manifold and the second manifold andincluding a dryer material disposed in the housing to dry fluid therein.

One advantage of the present invention is that a condenser with anintegral receiver dryer is provided for an air conditioning system of amotor vehicle. Another advantage of the present invention is that thecondenser has the receiver dryer incorporated into a manifold of thecondenser that has been increased in diameter. Yet another advantage ofthe present invention is that the condenser has an integral receiverdryer in the manifold which has fewer parts and compact installation.Still another advantage of the present invention is that the condenserhas an integral receiver dryer including a large single manifold anddryer material that perform as a receiver dryer. A further advantage ofthe present invention is that the condenser has an integral receiverdryer that includes a deflector in the manifold to direct refrigerant toupper passes of the condenser. Yet a further advantage of the presentinvention is that the condenser has an integral receiver dryer with atwo-piece integrated stamped manifold with multiple baffle depressionsfor flexible baffle locations as an option. Still a further advantage ofthe present invention is that the condenser has an integral receiverdryer with a modular capsule or desiccant bag for the dryer material.Another advantage of the present invention is that the condenser has anintegral receiver dryer with some phase separation.

Other features and advantages of the present invention will be readilyappreciated, as the same becomes better understood after reading thesubsequent description taken in conjunction with the accompanyingdrawings.
